# GraphQL MCP Server - Project Status
## Current Status: Production Ready
The GraphQL MCP Server is now fully functional, production-ready, and implemented in TypeScript with strong typing. It successfully implements the Model Context Protocol (MCP) for seamless integration with Claude Desktop, enabling dynamic access to any GraphQL API.
## Key Milestones Achieved
1. ✅ **TypeScript Implementation**: Completely rewritten in TypeScript with proper type definitions
2. ✅ **Dynamic Schema Introspection**: Server successfully introspects any GraphQL API and generates appropriate tools
3. ✅ **Full MCP Protocol Support**: Implements all required MCP endpoints with proper response formatting
4. ✅ **Smart Query Generation**: Builds optimized GraphQL queries with appropriate field selection
5. ✅ **Complex Input Handling**: Properly processes input objects and variable types
6. ✅ **Error Handling**: Robust error handling and propagation to client
7. ✅ **MCP-Compliant Response Format**: Returns results in the format expected by Claude Desktop
## Recent Updates
- **TypeScript Conversion**: Completely rewritten in TypeScript with proper type definitions
- **Strong Typing**: Added comprehensive type definitions for all components
- **Development Workflow**: Added improved development scripts for better developer experience
- **Documentation Update**: Updated documentation to reflect TypeScript conversion
## Type Safety Benefits
The TypeScript implementation provides significant benefits over the previous JavaScript version:
- **Compile-time Error Detection**: Catches errors during development before they reach users
- **Better IDE Support**: Improved code completion and type hints
- **Self-documenting Code**: Types serve as documentation for the codebase
- **Safer Refactoring**: Types ensure changes don't break existing functionality
- **Improved Maintainability**: Easier to understand and modify the codebase
## Known Limitations
- **Authentication Methods**: Currently only supports Bearer token authentication
- **Field Selection**: Uses a heuristic approach that may not be optimal for all schemas
- **GraphQL Directives**: Limited support for GraphQL directives
## Next Steps
1. **Enhanced Authentication**: Support additional authentication methods
2. **Schema Caching Options**: Add configurable caching strategies
3. **Advanced Mutation Features**: Add support for complex mutation input types and recursive fragments
4. **Testing Suite**: Develop comprehensive tests for different GraphQL APIs
5. **API Documentation**: Generate API documentation from TypeScript types
## Deployment Status
The server has been successfully tested with:
- Claude Desktop (macOS and Windows)
- Countries GraphQL API
- GitHub GraphQL API
- Various other public GraphQL endpoints
